Sri Lanka has experienced numerous man-made disasters and events that have profoundly shaped the nation‘s history, economy, and society. From the devastating civil war that lasted nearly three decades to industrial accidents, infrastructure failures, and the recent economic crisis, man-made disasters in Sri Lanka have caused immense human suffering and economic losses.
Man-made disasters are catastrophic events caused by human actions, decisions, negligence, or technological failures. Unlike natural disasters such as earthquakes or tsunamis, man-made disasters in Sri Lanka result from poor planning, inadequate safety measures, corruption, political conflicts, and environmental mismanagement. These disasters can be prevented or their impacts significantly reduced through proper governance, regulation enforcement, and community awareness.
The impact of man-made disasters in Sri Lanka extends beyond immediate casualties and property damage. They disrupt economic activities, undermine social cohesion, damage infrastructure, and create long-term environmental degradation. Recent decades have witnessed an increase in certain types of man-made disasters, particularly infrastructure failures, industrial accidents, and waste management crises, highlighting urgent need for improved safety standards and regulatory oversight.
The Sri Lankan Civil War represents the most catastrophic man-made disaster in Sri Lanka’s history, lasting from 1983 to 2009 and fundamentally altering the nation’s trajectory. The conflict between the government and the Liberation Tigers of Tamil Eelam (LTTE) claimed an estimated 70,000 to 100,000 lives over 26 years, though exact figures remain disputed. The war displaced hundreds of thousands of people, devastated infrastructure particularly in northern and eastern provinces, and created deep societal divisions that persist today.
The conflict officially began on July 23, 1983, when the LTTE ambushed an Army patrol in Thirunelveli, Jaffna, killing thirteen soldiers. This attack provided the pretext for the pre-planned Black July pogrom unleashed against the Tamil community in Colombo, in which 3,500-4,000 Tamils were killed. Before the pogrom, the LTTE had only 30 full-time members. Subsequently, thousands of outraged Tamil youths joined Tamil militant groups, marking the start of the civil war.
The war featured numerous massacres, suicide bombings, and attacks on civilians of all ethnicities. The LTTE gained international notoriety for carrying out attacks against civilians, using child soldiers, assassinations of politicians and dissenters, and pioneering the use of suicide bombings against military, political and civilian targets. In January 1996, the LTTE carried out one of its deadliest suicide bomb attacks at the Central Bank in Colombo, killing 90 and injuring 1,400. In July 2001, the LTTE attacked Bandaranaike International Airport, destroying eight military aircraft and four Sri Lankan Airlines planes, devastating the economy and causing tourism to plummet.
Major military operations resulted in massive casualties on both sides. The Battle of Mullaitivu in July 1996 left 1,173 army troops dead, including 207 officers and men executed after surrendering to the LTTE. The fall of Elephant Pass military complex in April 2000 left 1,008 soldiers dead. The LTTE also assassinated Sri Lankan President Ranasinghe Premadasa in May 1993 through a suicide bombing.
The war severely disrupted infrastructure and social life, especially in northern and eastern provinces. Entire towns were destroyed, roads and bridges damaged, schools and hospitals closed, and agricultural lands rendered unusable due to landmines. The LTTE’s improvised anti-personnel mines, known as “Jony mines,” led to approximately 6,000 post-war amputees in the Sri Lankan Army alone. The economic consequences have been profound and lingering, with the northern and eastern provinces experiencing significantly lower development indicators compared to other regions even 15 years after the war’s end.
The final phase of the war in 2009 was particularly brutal. The Sri Lankan armed forces carried out an avalanche of atrocities: they bombed No Fire Zones, shelled hospitals, fired on LTTE combatants that surrendered, carried out enforced disappearances, and denied humanitarian aid such as food and medicine to civilians in camps. The “Sri Lankan option” set a precedent for the elimination of dissent that has drawn international criticism and comparisons to other conflicts.
The 2019 Easter Sunday bombings represent one of the deadliest terrorist attacks and man-made disasters in Sri Lanka, shocking the nation and the world. On April 21, 2019, Easter Sunday, three churches and three luxury hotels in the commercial capital Colombo were targeted in a series of coordinated ISIS-related terrorist suicide bombings. Later that day, two smaller explosions occurred at a housing complex in Dematagoda and a guest house in Dehiwala.
A total of 269 people were killed (later revised to 270 when a victim died of injuries in 2024), including at least 45 foreign nationals, three police officers, and eight suicide bombers. An additional 500 were injured. The church bombings were carried out during Easter services in Negombo, Batticaloa and Colombo, targeting Christians during worship services. The hotels bombed included the Shangri-La, Cinnamon Grand, Kingsbury and Tropical Inn, targeting guests during breakfast.
The attacks specifically targeted Sri Lanka’s minority Christian community, which accounts for less than 10% of the country’s total population. The Shrine of St. Anthony in Kotahena, Colombo was the first to be hit, followed by the Church of St. Sebastian in Negombo where 115 people died, including 27 children. The Zion Church in Batticaloa lost 30 people when the suicide bomber detonated his device in the churchyard after being denied access to the church during the service, killing many children from the Sunday school.
According to Sri Lankan government officials, all eight suicide bombers involved in the attacks were Sri Lankan citizens associated with National Thowheeth Jama’ath (NTJ), a local Islamist militant group with suspected foreign ties. State Minister of Defence Ruwan Wijewardene theorized that the attack was in retaliation for the Christchurch mosque shootings which occurred the month before on March 15, 2019.
Security lapses leading to the attack, and the Sri Lankan government’s failure to act on intelligence warnings, were highlighted during inquiries. Information was available about the attacks, but adequate precautions were not taken. On January 12, 2023, the Supreme Court of Sri Lanka ruled that then-incumbent president Maithripala Sirisena and several other government authorities at the time failed to act on intelligence, and were ordered to pay compensation to victims.
The bombings had severe economic consequences, causing tourism—a vital foreign exchange earner for Sri Lanka—to plummet. The attacks contributed to the economic instability that would eventually culminate in the 2022 economic crisis. The attacks also heightened religious tensions and raised serious questions about intelligence failures and government accountability.
The Meethotamulla landfill collapse in April 2017 represents a preventable man-made disaster in Sri Lanka caused by decades of poor waste management, negligence, and broken promises. On the afternoon of April 14, 2017, during the Sinhalese New Year celebrations, a large section of the Meethotamulla garbage dump collapsed onto surrounding houses, burying homes and killing residents.
According to the Disaster Management Centre, the landslide caused 32 deaths with 8 more missing, and affected a total of 1,765 people. The collapse destroyed 146 houses completely, with 60 houses fully destroyed and 27 houses partially damaged. Many victims were celebrating the Sinhalese New Year holiday when the disaster struck, adding to the tragedy as families were gathered together.
The 21-acre garbage dump site had reached a height of 48.5 meters (159 feet) before collapsing. The site received between 750 and 1,200 tonnes of garbage daily from Colombo municipality. Intense rainfall during April 11-13, 2017, combined with a fire at the dump hours before the collapse, destabilized the massive pile of rotting debris, causing it to shift and then collapse catastrophically.
Labeling it a “disaster” is misleading because it did not just happen—it was allowed to happen. The hazard of a garbage dump came to the community in Meethotamulla, not the other way around. Behind the tragedy is a litany of broken promises, including an assurance by the Prime Minister himself in 2015 to solve the problem within six months. Protests by residents were met with tear gas or batons. A group of residents of Meethotamulla approached the Supreme Court in 2014 seeking to stop the dumping of garbage, but their concerns were not adequately addressed.
President Maithripala Sirisena appointed a Presidential Commission of Inquiry headed by Justice Dr. Chandradasa Nanayakkara on April 26, 2017. The commission’s report found that Colombo Municipal Commissioner V.K.A. Anura failed to take “necessary action to avert the garbage dump collapse despite he being informed by the officials on the looming threat well in advance.” Anura was removed from office in early 2018 based on the commission’s recommendation.
The Auditor General issued a report in May 2018 finding the Colombo Municipal Council (CMC) responsible for the death of 32 people and for the damage caused to properties. It found the CMC responsible for not properly disposing waste and not properly carrying out payment of compensation to the affected. The disaster highlighted systemic failures in urban planning, waste management, and governance that continue to pose risks in other locations across Sri Lanka.
The Sri Lankan economic crisis of 2022 represents the worst economic disaster in Sri Lanka’s history since independence in 1948, creating humanitarian suffering and political upheaval. The crisis began due to multiple compounding factors including tax cuts, money creation, a nationwide policy shift to organic farming, the 2019 Easter bombings, and the impact of the COVID-19 pandemic. The subsequent economic hardships resulted in the 2022 Sri Lankan protests that ultimately toppled the government.
In early 2022, Sri Lankans started experiencing power cuts and shortages of basics such as fuel, medicine, and food. The rate of inflation rose to 50% annually, then surged past 70%. By April 2022, the government could no longer meet its external debt obligations and suspended payments on approximately $46 billion in foreign debt, marking the first sovereign default in the Indo-Pacific in over two decades. Foreign reserves plummeted to $1.9 billion as of March 2022, insufficient to pay foreign debt obligations of $4 billion.
The fuel shortage caused petrol and diesel prices to rise dramatically. The country ran short of fuel for essential services such as buses, trains, and medical vehicles. In June 2022, the government banned the sale of petrol and diesel for non-essential vehicles for two weeks, and sales of fuel remained severely restricted. Schools had to close, and people were asked to work from home to help conserve supplies. Daily power cuts were imposed, reaching 15 hours at the peak of the crisis in April 2022.
The social consequences were severe. Extreme poverty quadrupled between 2019 and 2022. A food emergency was declared in August 2021. Public anger, fueled by worsening living conditions and perceived governmental negligence, erupted into mass protests that paralyzed major cities in March 2022. Tens of thousands of supporters of opposition parties carried out protests demanding that the government solve the financial crisis and resign. When Namal Rajapaksa arrived for the opening ceremony of a sports ground in Bandarawela on March 30, angry locals blocked the road demanding fuel.
Four fatalities occurred due to fatigue and violence in queues at fuel stations. On May 9, Prime Minister Mahinda Rajapaksa resigned after protests turned violent. The crisis culminated in July 2022 with President Gotabaya Rajapaksa fleeing the country following massive protests. The economic crisis was further exacerbated by the repercussions of the 2022 Russian invasion of Ukraine, as Russia was the second largest market for Sri Lanka’s tea exports, and tourism relied heavily on Russian and Ukrainian guests.
By 2025, Sri Lanka has begun economic recovery following an IMF bailout program and debt restructuring. However, the social costs have been significant. Higher taxes strained households and businesses, while utility price hikes led to steep increases in living costs and higher operating expenses for small and medium-sized enterprises. The crisis exposed decades of economic mismanagement, structural vulnerabilities, and policy miscalculations that undermined the nation’s economic stability.
Deforestation represents an ongoing man-made disaster in Sri Lanka that threatens biodiversity, increases natural disaster risk, and undermines livelihoods. Sri Lanka’s forest cover decreased dramatically from 80% in 1820 to 43% in 1948, partly caused by British colonialism which increased tea, coffee, and rubber plantations. The natural forest cover further decreased to 23% in 2000. In 2010, only 29% of Sri Lanka’s area was covered by forests, including forest plantations.
Drivers of deforestation include population increase, road construction, timber production, agricultural development, and forest clearing by private businessmen. During the civil war period, forests were strategically removed to provide less cover for the enemy, adding security concerns to development pressures. The main four reasons for deforestation in Sri Lanka are encroachments due to agriculture, gem mining, illegal logging, and development projects.
The consequences of deforestation are profound and far-reaching. Deforestation has increased soil erosion, landslides, floods, fauna and flora degradation, and damage to human lives and properties. Loss of biodiversity threatens survival of numerous endemic species, as Sri Lanka is one of the world’s biodiversity hotspots. Trees play a crucial role in maintaining soil health by preventing erosion; their removal exposes soil to wind and rain, leading to increased erosion and loss of fertile topsoil.
Forests act as carbon sinks, absorbing carbon dioxide from the atmosphere. Deforestation releases stored carbon, contributing to greenhouse gas emissions and exacerbating climate change. This creates a vicious cycle, as climate change further threatens forest ecosystems. Deforestation also disrupts the water cycle, leading to altered water availability and increased flooding in some areas and drought in others.
Mangrove forests have been decreased by 70% since 1915, reduced primarily by agriculture and aquaculture systems like shrimp farms. The increased human activities such as illegal timbering, clearing for settlements and business, dumping municipal and urban waste, and land-filling for housing development have caused serious pressure to mangrove environments. This has intensified flooding and erosion in lagoon and coastal areas.
Industrial hazards represent growing man-made disaster risks in Sri Lanka as the country’s industrial sector expands. With industrial development during the past decade, Sri Lanka is experiencing chemical disasters more frequently than in early days. Sri Lanka’s chemicals industry is rapidly expanding due to various government initiatives to improve economic development, creating new risks of chemical accidents including spills, fires, and explosions.
The X-Press Pearl ship disaster in May 2021 represents the most serious recent industrial and environmental disaster. A cargo ship carrying chemicals caught fire off the coast of Sri Lanka, creating an environmental catastrophe. The ship carried 46 different chemicals including nitric acid, sodium dioxide, copper, and lead. For days it burned off the coast, and eventually sank half-submerged, with its hull resting on the shallow ocean bed.
The most visible impact was billions of tiny plastic pellets (nurdles) that washed up on beaches, stretching as far as the eye could see. These pellets, used to make nearly all plastic goods, can take between 500 to 1000 years to decompose. Fish were washed up with bloated bellies and pellets stuck in their gills. The plastic pellets were carried by ocean currents to shores around Sri Lanka and to beaches hundreds of kilometers away.
The chemical pollution from the X-Press Pearl will likely affect Sri Lanka for decades. Nitric acid, sodium dioxide, copper, lead, and other dangerous chemicals leaked into the water, making their way into local marine life. Fishermen reported that fish breeding grounds in coral reefs were destroyed due to dangerous chemicals. One fisherman stated: “The fish are bred in the coral reefs in the area and authorities are saying that all those breeding grounds are destroyed. There is no other option than jump into the sea and die.”
Air pollution is another serious industrial hazard. Colombo, Kandy, and Kurunegala have been identified as the most polluted cities in Sri Lanka due to high traffic congestion and increasing urbanization. In Sri Lanka, automobile emissions account for about 60-70% of total urban air pollution, while industrial sources including coal and thermal power plants contribute significantly. In December 2022, following cyclonic conditions, air quality in Colombo reached the dangerous level of 169 on the air quality index, compelling the government to close schools in smog-choked towns.
Water pollution from industrial sources is severe in major river basins. The Kelani River, one of the most polluted rivers in the country and a major source of drinking water for nearby communities, is being significantly impacted by discharge of industrial effluents. Studies revealed that all industries surveyed were discharging large amounts of pollutants into rivers, exceeding permitted limits established by Sri Lanka’s Central Environmental Authority. High COD levels indicate significant organic matter and chemical pollution. The Maha Oya, one of Sri Lanka’s largest rivers, was affected by factories discharging effluents, dyes, and chemicals, causing many people in the town of Alawa to suffer from skin diseases and other health issues.
Dam failures represent critical infrastructure disasters in Sri Lanka, with the potential for catastrophic loss of life and property. The unprecedented floods in December 1957 in the dry zone caused breaching of 35 large dams, 53 medium dams, and 1,500 small dams within a 3-5 day period, causing heavy damage to irrigation infrastructure. Luckily, sufficient time was available for issuing pre-warning, and lives lost were reported to be very few.
The Kantale Dam disaster in January 1986 represents the most deadly modern dam failure. The breach killed 127 people, affected 10,864 residents, destroyed 1,200 houses, and substantially damaged agriculture, commercial and public infrastructure and private assets. More than 100 people who lived in a village called Kovilgama, downstream from the tank, lost their lives. Around 2,000 acres of paddy land were silted.
Following the disaster, the Irrigation Department established a new Dam Safety division. The Swedish company SKANSKA was assigned to rebuild the breached bund and sluice, with reconstruction completed within two years. The tank was again impounded in the 2008 Yala season. The disaster prompted significant improvements in dam safety monitoring and emergency preparedness.
Many of Sri Lanka’s dams are aging and have various structural deficiencies and shortcomings in operation and monitoring facilities. A World Bank-supported safety assessment of 32 large dams showed signs of risk and confirmed the need for urgent action including structural improvements. The 2004 tsunami disaster further deepened the urgency for protecting the public from potential dam failures, leading to the establishment of the National Council for Disaster Management.
Typical safety issues commonly observed in dams include erosion of upstream and downstream slopes due to wave action, slope sloughing/slips, erosion of abutments, settlement and cracks along dam crests, damage to outlet and intake structures, and cracks in concrete spillways and outlet gates. The Randenigala dam shows rising of the core and cracking in the spillway control room. Kalawewa dam has concerns about ancient sluice sections and seepage through rubble masonry works. Nachchaduwa dam has many safety issues including spillway inadequacy, operational problems with outlet gates, collapsed embankment slopes, leakage through the dam body, and sand boils at the downstream toe.
Road traffic accidents represent the most consistent man-made disaster in Sri Lanka, claiming approximately 3,000 lives annually and injuring 8,000 more. Sri Lanka suffered an annual average of 38,000 crashes in recent years. The estimated annual road crash deaths per capita is the highest among immediate neighbors in South Asia and five times that of the best performing countries in the world. Road traffic crashes cost Sri Lanka around 4.9% of its gross domestic product.
The rapid growth in vehicle ownership—67% between 2011 and 2018—and the diversity of motorized and non-motorized traffic of varying sizes and speeds leaves vulnerable road users without adequate protection. More than 90% of crash victims are pedestrians, cyclists, and motorcyclists. Over two-thirds of road crash victims are productive, working age adults between 15-64 years of age, with 91% being male.
According to police data, in 2022 there were 2,515 deaths from road accidents. The breakdown by road user type shows that motorcyclists (820 deaths) and pedestrians (792 deaths) suffered the highest fatalities, followed by passengers (314 deaths). Police reported that more than 90% of reported crashes were due to reckless driving, including overtaking (16.5%), diversion (14.5%), speed driving (13.3%), and alcohol consumption of the driver (4.5%).
Although movement restrictions during the COVID-19 pandemic were expected to improve road safety by keeping people off the roads, this did not occur in Sri Lanka. Road accidents and fatalities did not significantly drop between 2020 to 2022. Traffic police reported more accidents related to motorized two and three-wheel vehicles, mostly related to speeding, reckless driving, drunk driving, and drivers not adhering to road rules.
Corruption is also a contributing factor, as some drivers’ licenses are obtained by unqualified persons through corrupt means. Well-to-do and well-connected traffic offenders are able to escape punishment via business and other connections. This situation undermines the effectiveness of traffic enforcement and contributes to the ongoing high rate of accidents.
Building collapses represent recurring man-made disasters in Sri Lanka caused by negligence, improper design, incorrect construction practices, inadequate maintenance, improper alterations, and use of bad materials and workmanship. Multiple building collapse incidents have resulted in deaths, injuries, and significant property damage, highlighting systemic failures in building regulation and enforcement.
The Wellawatta building collapse on May 18, 2017, killed 2 people and injured 27 construction workers when a reinforced concrete floor slab of a hotel building collapsed. Investigations revealed that the building had been designed for 5 stories, but another 2 floors had been added without getting consent of the design engineer or approval of the Municipal Council. The structure was not strong enough to support the loads at the time of failure. Design alterations had been carried out time to time, adding extensions horizontally and vertically to the original structure, all without proper authorization.
The Grandpass building collapse on February 14, 2018, killed 7 people and injured many others when a single-story old masonry building collapsed in Colombo. It is suspected that influence of construction activities of a nearby site caused this failure, apparently due to negligence. A building collapse at Negombo on August 17, 2017, injured several workers when part of a reinforced concrete building under construction collapsed, with suspected reasons being problems with formwork and the maturity of the structure below.
Most recently, on October 30, 2024, five two-story buildings on Galle Road in Panadura collapsed simultaneously after work on the drainage system along the street. The Panadura Municipal Council had hired a contractor who used a backhoe to dig up drains and clear the drainage system, destabilizing the foundations of the adjacent buildings. Fortunately, no injuries were reported in this incident.
The main reasons for building collapses in Sri Lanka include negligence, improper design, incorrect construction practices, inadequate maintenance, improper alterations without structural assessment, bad materials and workmanship, and violation of building codes during design and construction. Many lives and millions of rupees could be saved if proper engineering practices were followed and building regulations properly enforced.
The National Building Research Organisation (NBRO) conducts forensic investigations of major building failures, though such investigations are not common in Sri Lanka. Reasons include lack of experts, high cost, lack of tools and equipment, lack of confidence in engineers to undertake such investigations, and lack of perceived need for investigations after failures. However, proper forensic investigation is essential for learning from failures and preventing future disasters.
Illegal mining and unsustainable resource extraction represent ongoing man-made disasters in Sri Lanka that damage ecosystems, increase natural disaster risk, and harm communities. River sand mining occurs at high rates in Sri Lanka, as miners and other beneficiaries can make substantial money from the practice. A survey by the University of Colombo found that ten times as much sand was being extracted as permits allowed.
The illegal removal of sand from riverbeds for the construction industry causes severe environmental problems. Sand mining lowers river beds, changes river courses, damages aquatic habitats, and increases flood risk. In the Kelani River, sand mining is particularly severe, with the salt wedge extending inwards to Ambatale (about 14 km from discharge point) on several occasions due to lowering of river beds at lower reaches. This is a serious concern as much of the potable water supply for Colombo is extracted from the Kelani River at Ambatale.
Coral mining, another destructive practice, threatens coral reefs that are essential for protecting coasts, supporting fisheries, and attracting tourists. Unsustainable coastal resource utilization including coral mining, sand mining, and cutting mangroves has increased around the island. Lack of planning and management of resources has intensified pollution and erosion, with the worst affected being the southwest coastal zone.
Gem mining contributes to deforestation and environmental degradation. Mining and quarrying for minerals and stones for construction involves clearing large areas of forest, leading to habitat destruction. Unsustainable agricultural practices, often associated with encroachment into forest areas, also contribute to soil degradation and desertification, particularly in the dry zone.
New regulations and enforcement efforts by the Global Water Partnership and government authorities have led to stricter controls on illegal sand mining. Direct action programs to protect river banks and replant river reservations have been implemented in several river basins. However, continued vigilance and enforcement are necessary to prevent ongoing environmental damage and disaster risk from illegal resource extraction.
